C. P. VAUCLAIN ET AL PROCESS OF MAKING AXLE BOXES Filed Aug. 5 1929 2 Sheets-Sheet 2 Patented May 5, 1931 UNITE TTES PATENT? oFFmE CHARLES PARRY VAUGLAIN, F DREXEL HILL, AND FRANK E. IMERKLINGER, 0F PHILA- DELPHIA, PENNSYLVANIA PROCESS OF MAKING AXLE BOXES Application filed August 5, 1929. Serial No. 383,531.

Our invention relates to improvements in the process of making the axle boxes disclosed in the application filed by us on the 2nd day of April, 1929, under Serial No. 351,959.

The object of the present invention is to make the body portion from a wrought metal tube, the tube being shaped, after which the pedestal guide rings are mounted on the body portion.

In the accompanying drawings: Fig. 1 is a front view of an axle box made in accordance with our invention;

Fig. 2 is a plan View; Fig. 3 is a perspective view of the axle box with the parts assembled, with theexception of the outerring;

Fig. 4 is a detached perspective view of the outer ring which is welded to the body portion;

Fig. 5 is a vertical sectional view of the axle box;

Fig. 6 is a detached perspective view of the wrought metal tube from which the body portion is made; and

Fig. 7 is a detached perspective view of the body portion made from the tube shown in Fig. 6.

The axle box illustrated in the drawings is arranged to receive a roller-bearing of a standard type, but it will be understood that the box can be of any design desired without departing from the scope of the invention.

1 is the body portion of the axle box, and 22a are the two ring sections, shaped at each side as shown in Figs. 2 and 3 to form guides 33 which fit the pedestals of the frame in which the box is mounted.

The body portion 1 of the box is made from a wrought metal tube 1a, Fig. 6. This tube is heated to a proper degree and a rear flange 4 is formed on the rear end of the tube, the forward end being rounded as at 5, leaving an opening 6 therein at the end of the body 45 portion less in diameter than the body portion. This opening is clearly shown in Fig. 5.

After the body portion has been made from the tube 1a, the two rings 2-200 are forced onto the body portion, and the inner ring 20 is spaced from the flange 4 of the body por- 5 tion by spacing blocks 7 (Fig. 3), and the two rings 22a are spaced apart by a block 8 which forms an equalizer seat. This seat has a rib 9 which extends into an equalizing beam, the beam of any'suitable type.

Welded to the front of the body portion 1 is a ring 10 having an opening 11 of the same size as the opening 6 in the body portion. This ring is welded to the body portion and forms the support for the lid of the box.

We claim:

1. The process herein described of making axle boxes, said process consisting in cutting a tube to the proper length; forming a flange on one end of the tube and rounding the 0pposite end of the tube to form the front end of the box; mounting on the body portion two ring sections spaced apart, the ring sections having pedestal guides formed integral therewith; and welding the parts together.

2. The process herein described of making axle boxes, said process consisting in cutting a tube to the proper length; forming a flange on one end of the tube and rounding the opposite end of the tube to form the front end of the box mounting on the body portion two ring sections spaced apart, the ring sections having pedestal guides formed integral therewith; securing a ring to the front of the box and locating an equalizer seat between the two rings; and welding the parts together.

3. The process herein described of making axle boxes, said process consisting first of heating a wrought metal tube and shaping the .85 ends of the tube to form the front and rear ends of the box; and securing to said tubular body portion thus formed, two pedestal guides, said guides being spaced apart and secured to the body portion by Welding.

4. The process herein described of making axle boxes, said process consisting of cutting a Wrought metal tube, which is circular in cross section, to a given length; heating the tube and shaping the ends of the tube to form the front and rear ends of the box; applying to the body of the boX thus formed, ring sections having pedestal guides, the ring sections being spaced apart; and securing the said ring sections to the body of the box by Welding.
